Abstract

PURPOSE:To prevent absence transfer from not being released forgetfully by sending a transfer message out to a telephone set at an absence transfer origin when an incoming call arrives while the absence transfer is set. CONSTITUTION:When there is the incoming call for the telephone set where the absence is set, a central control part 8 reads data showing that the absence transfer is set and reads the telephone number of an absence transfer destination out of a memory part 7 and controls a voice reproduction part 6 to reproduces a transfer voice message stored in a transfer message storage part 5. The reproduced transfer voice message is sent out to the speaker of the key telephone set at the absence transfer origin. At this time, an incoming tone is sent to the telephone set at the absence transfer destination. Consequently, the setting of the absence transfer is informed on the telephone set at the absence transfer origin and the absence transfer is prevented from not being released forgetfully.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone device having a call forwarding function.

[0002]

2. Description of the Related Art Conventionally, a key telephone housed in a key telephone apparatus is designed to blink a predetermined lamp and display a message to that effect when call forwarding is set. When the telephone is equipped with an indicator, the fact is displayed on the indicator.

[0003]

However, only by such a display state on the telephone and a blinking state of the lamp,
Even if he / she is seated, he / she does not know whether or not he / she is currently set to forward call unless he / she looks at the telephone, which is a drawback that he often forgets to cancel the forward call. For this reason, especially when there is a key telephone in each room, you can set call forwarding to go to the other room that is the transfer destination, and then return to your own room There was a problem that it would continue to be transferred.

[0004]

In order to solve the above problems, the present invention provides a transfer message storage unit for storing a transfer voice message, and a voice reproducing unit for reading voice message data from the transfer message and reproducing the voice message data. , When the incoming call arrives at the transfer-source button telephone, the means for controlling the voice playback unit to send the transfer voice message in the transfer message storage section to the speaker of the transfer-source button telephone, and the incoming call to the transfer-source button telephone And a means for sending a ring tone to the transfer destination button telephone.

[0005]

When an incoming call arrives at the transfer source telephone when call forwarding is set, a ring tone is transmitted to the transfer destination telephone and a transfer voice message is transmitted to the speaker of the transfer source telephone.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.
The key telephone device of this embodiment includes key telephones 20 to 2n provided with a speaker in the main unit 1 and an office line L1 as an outside line.
The main device 1 includes a switch unit 2, a terminal interface unit 3, a station line interface unit 4, a transfer message unit 5, a voice reproducing unit 6, a memory unit 7, and a central control unit 8. ing.

The switch section 2 connects the terminal interface section 3 and the office line interface section 4, and the terminal interface section 3 is an interface section between the key telephone sets 20 to 2n and the main unit 1. Sends and receives control signals with each key telephone. Also,
The office line interface 4 is an interface portion between the office line and the main device 1, and performs transmission of a dial signal to the office line and detection of an incoming call from the office line.

Further, the transfer message storage section 5 is a voice message for informing that the telephone of the transfer source has received an incoming call during the absence transfer, for example, a voice message saying "There was an incoming call. Is to remember. The voice reproduction unit 6 reproduces the voice message data stored in the transfer message storage unit 5 when an incoming call is received by the telephone of the absence transfer source. Further, the memory unit 7 stores set / reset data of absent transfer, an absent transfer destination number, etc., and the central control unit 8 controls the entire apparatus.

Next, the operation of the call forwarding set will be described. For example, when the key telephone 20 operates a special number to enter the call forwarding set mode, and when the telephone number of the key telephone 21 is designated as the call forwarding destination telephone number at this time, the information is transferred to the central control unit 8 via the terminal interface 3. It is sent and stored in the memory unit 7.

When an incoming call arrives at the key telephone 20 at such a time, the central control unit 8 reads the set / reset data of the absence transfer and the telephone number of the absence transfer destination from the memory unit 7, and "the key telephone 20 is absent. When the data indicating that the transfer destination is the key telephone 21 in the transfer set is obtained, the switch unit 2 is controlled to connect the voice reproducing unit 6 and the terminal interface unit 3, and then the voice reproducing unit is controlled. , The voice message data stored in the transfer message storage unit 5, that is, “there is an incoming call.

The voice message data thus reproduced is sent to the speaker of the key telephone 20 which is the transfer source through the switch section 2 and the terminal interface section 3.
Next, the central control unit 8 controls the switch unit 2 to disconnect the audio reproduction unit 6 and the terminal interface unit 3,
A ring tone is sent to the key telephone 21 which is the transfer destination.

As described above, when an incoming call arrives when the absence transfer is set, an announcement indicating that the absence transfer is in progress is made by a voice signal from the speaker of the absence transfer source.

[0013]

As described above, according to the present invention, when an incoming call arrives at the transfer source telephone when call forwarding is set, a ring tone is sent to the transfer destination telephone and the speaker of the transfer source telephone is sent. Since the transfer voice message is sent to, it is possible to know that the absence transfer is in progress, and therefore it is possible to prevent forgetting to cancel the transfer.
